Thanx.

I got the scipy and core sources, installed the prerequisites (debian 
packages) mentioned in scipy/INSTALL.txt (ATLAS, ...).

When I run

	scipy.test()

I get a floating point exception:

Should array indices start at 0 or 1? My compromise of 0.5 was rejected 
without, I thought, proper consideration.
